Of all the negative things I can say about OVA3, and I can say a lot, boring and dull is not one of them.

This is not something i can say about OVA4.

Animation:

Where is it? The animation and art work is bare bones, everyone basically just stands around talking about nothing. This is a far cry from the amazing cel work done in OVA 1 and OVA 2.

Story:

Man, my favorite part of Tenchi Muyo, the part that truly brought me into this show all those years ago, is where they all stand around talking about characters from other shows and spin offs.

I remember, back in OVA
1, being absolutely riveted as everyone sat around a table talking about silk. Or or! I remember that part in OVA season 2, where they spent a whole episode around a table, talking about characters from other shows! Oh man, i just loved it in OVA 1 where instead of fighting Kagato, they sat around a table and talked. Or that part in OVA2 where they dealt with Dr. Clay, by sitting around a table talking. I just loved when they talked about Zero, but never actually showed her. Oh and how could i forget that episode in OVA 3 where a bunch of characters i have never seen all sat around a table talking about who will get married next.

Oh! My absolute favorite part was in OVA2 where half of a episode was spent around a table advertising a show that came out 7 years prior? Man i just loved that part.

When I watch Tenchi Muyo, I want to watch Tenchi Muyo. I want to see the antics of Tenchi, Ayeka, Ryoko, Mihoshi, Washu, Sasami and Ryo-ohki. Not characters from GXP, and not characters from Gemini. For example, none of the original characters even show up in OVA2 until past the 10 minute mark. As some one who has no interest in GXP or Gemini, i had just about no clue who any of these people are. And even worse they don't even show who all they are talking about, so i hope you have all their names memorized!.

Episode 1:
~ Scene: Everyone is sitting at a table ~
"Hey hows is Character X from GXP?" "Oh he is doing good"
"Hey how is Character Y from Gemini doing?" "Not to bad"
"Hey hey, you remember Character Z from GXP?" "Oh yeah, i heard he is still in space"
Repeat until end credits.

Oh and now Tenchi has yet another sister who wants in his bed right from the get go.

Music:

What music? There is a opening and ending song, and that about it. Background music is nearly non-existent.

This is not my Tenchi Muyo Ryo-ohki.

You could have removed all of the original characters: Tenchi, Ryoko, Ayeka, Sasami, Ryo-ohki, Washu and Mihoshi from this show and it would not have made one difference at all. I mean, its not like they had any screen time here anyways.
